Temporary Buildings Applications
1. What do I need to do to obtain the Permit to Use (PTU)?
The owner who intends to erect a temporary building must engage a professional civil or structural engineer to design, supervise, inspect the erection of the temporary building and submit the application for PTU on behalf of the owner via CORENET e-Submission.
2. Is there a simplified process to obtain PTU for temporary building with previously approved design?
A simplified PTU submission and approval process is available for temporary buildings (e.g. containers, standardized or modularised structures used in events) with previously approved design. The owner (through his/her appointed Professional Engineer (PE)) will first need to have obtained an earlier approval from the Commissioner of Building Control for the design (plans and calculations) for their temporary buildings. For subsequent erection of temporary buildings using the same previously approved design, the same owner (through the same appointed PE) can apply for PTU based on the previously approved design, by citing the earlier approval reference number (without the need to resubmit plans and calculations in this subsequent PTU application). Once the submission is in order, a Preliminary Approval will be issued for the erection/installation of temporary buildings. The PE is still required to supervise the erection/installation and submit the relevant Certificates of Supervision to BCA prior to issuance of the PTU
3. What documents am I required to submit during the CORENET e-Submission?
An application for a PTU for the temporary building shall be accompanied by –
a. Where applicable, a copy of the written permission issued by the competent authority under the Planning Act (Cap. 232) in respect of the proposed temporary building;
b. A notification, signed by the temporary building owner, of the engagement of a professional engineer;
c. A location plan indicating the location of the temporary building;
d. Plans and Design of the individual structures for submission signed by the applicant and the Professional Engineer (PE) where applicable, with the standard temporary building endorsement by PE on the plan;
e. Design / Structural Calculations (PE Assessment);
f. Where the temporary building owner is not the owner of the premises on which the temporary building will be erected, written consent of the owner of the premises for the application to be made.
g. i. A fee of $200 for every 100 square metres, or part thereof, of the statistical gross floor area of the temporary building or buildings in the application;
ii. A fee of $200 for each structure in an application in which the temporary building or building have no meaningful or measureable statistical gross floor area;
Note: Item (a) is not applicable to all advertising structures
Pertaining to items (d) and (e) for temporary buildings submitted under the simplified PTU approval process (based on a previously approved design), the PE would only need to cite the earlier approval reference number.

The owner of the temporary building must demolish the temporary building within 14 days after the lapsing or revocation of the preliminary approval or expiry of revocation of the PTU and notify the CBC of the demolition within 7 days after the temporary building is demolished. It is an offence under the regulation 16 for failing to do so.
9. Can I extend the PTU upon its expiry?
An owner who is granted the PTU may, at any time before the expiry of the PTU, apply to the CBC for an extension of the permit and the extended use will be allowed at CBC’s discretion. Where the application to extend a PTU relates to a temporary building under paragraph (b) of the definition of “temporary building” in the Act, the PTU will not be extended such that the aggregate period of the PTU and all extensions of the PTU exceeds 72 months.
